Question
I was recently given a really beautiful orchid, i think it is a miltoniopsis (or miltonia? i'm not sure of the difference) but im very concerned because it looks like its slowly dying! Its leaves are still upright but all of its flowers are drooping.  I have been careful not to overwater and it is not in direct sunlight. My flat is pretty warm tho (about 26C). Do you think this could be the problem? I have considered putting it outside on my balcony at night.  Would you recommend this? Any other thoughts would be much appreciated! I have put a picture of the plant online at http://www.flickr.com/photos/56982753@N00/
Thanks,

Abi

Answer
Thank you for the beautiful picture of a Pansy Orchid (Miltoniopsis).  These hybrids come from species native to the high elevations of Colombia.  They want temperatures of 15-25C and nighttime humidities of 60 - 80 percent. When in new growth, they need frequent watering and the water should be low in salts (eg rainwater).  Use a weak plant food with each watering (1/4 tsp /gal).  They need an annual repotting in fresh orchid potting mix as they are subject to root rot.  Best time to repot is when new growth is starting.  Miltoniopsis flowers are not long lasting and their life span is greatly reduced by warmer temperatures. (Notice how delicate the flowers are?)

Miltoniopsis are among the most beautiful and delicate of the orchids and have proven a considerable challenge to most orchid growers.

I agree that putting it on the balcony at night would be helpful.  Anything you can do to increase nightime humidity would also be helpful, but be sure to increase air movement as the humidity increases.
